A Study on the Effect of Initial Shear Stress on Dynamic Properties of Saturated Clay

Abstract:

Through a series of tests on saturated remoulded clay, initial shear stress on dynamic shear modulus and damping ratio under the condition of large strain(>10-3) is examined. The test data indicate that initial shear stress effects on stress-strain relation and dynamic modulus and damping ratio are obvious. With the initial shear stress increasing, the characteristic of the stress-strain relation changes from cyclic deformation to accumulative deformation, and there is difference in variation pattern of dynamic shear modulus and damping ratio with cyclic number increasing.
